Not sure if something is SF? Then post it! Science Fiction, Fantasy, Alt. History, Postmodern Lit., and more are all welcome here. The key is that it be speculative, not that it fit some arbitrary genre guidelines.

The Zeroth Law: Our guidelines were designed to foster a diverse and welcoming discussion community while avoiding drama, flamewars, and promotional activity. All mod actions will be taken with these goals in mind. For more explanation, see our rules wiki page.

Be civil. Don't be a dick or a bigot. If you see uncivil behavior, downvote, report, and move on.

Do not make image posts, or otherwise fish for karma. If it's worth posting, it's worth posting as a self-post with context. See r/SpecArt for SF art.

Print SF can include books, stories, ebooks, graphic novels, comics, webcomics, manga, radio plays, music, and more. Posts primarily about TV shows, movies, or short films will be removed, even adaptations. Do not complain about works not fitting your personal definition of "science fiction".

Audio/ebook "deals" posts should be tagged in the post title with [region] and [platform]. For example, [USA][Kindle] Such-and-such book by so-and-so is only $2.99!

Spoiler tags are courtesy, not required. Comments with spoilers will not be moderated, and hidden spoilers are discouraged in discussions about individual books. Use common sense when reading about a book or author you don't wanted spoiled.
